Data compression is the compacting of information by reducing the number of bits that are stored or transmitted. In this way, the compressed info needs less disk space than the original one, so a lot more content could be stored on the same amount of space. There're many different compression algorithms that function in different ways and with several of them just the redundant bits are erased, which means that once the info is uncompressed, there's no loss of quality. Others remove excessive bits, but uncompressing the data afterwards will lead to reduced quality in comparison with the original. Compressing and uncompressing content takes a huge amount of system resources, especially CPU processing time, therefore each and every web hosting platform that employs compression in real time should have adequate power to support that feature. An example how information can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" what number of sequential 1s or 0s there should be instead of storing the entire code.

Data Compression in Shared Website Hosting

The ZFS file system which runs on our cloud hosting platform employs a compression algorithm called LZ4. The latter is considerably faster and better than any other algorithm available on the market, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard disk drive, which improves the overall performance of websites hosted on ZFS-based platforms. Since the algorithm compresses data really well and it does that very quickly, we can generate several backups of all the content stored in the shared website hosting accounts on our servers daily. Both your content and its backups will require reduced space and since both ZFS and LZ4 work very fast, the backup generation will not influence the performance of the web hosting servers where your content will be stored.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account shall be created on a cloud platform that runs on the advanced ZFS file system. The aforementioned uses a compression algorithm known as LZ4, that is much better than other algorithms when it comes to compression ratio and speed. The gain is visible particularly when data is being uncompressed and not only is LZ4 faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a HDD. That is why websites running on a platform that employs LZ4 compression perform faster since the algorithm is most effective when it processes compressible data i.e. web content. One more advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep take a lot less space and they are generated faster, which allows us to store multiple daily backups of all your files and databases.
